Power MOSFET/IGBT Component – Computer, Electronic and Optical Product Manufacturing

Component Specifications

Definition

Power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) and IGBT (Insulated-Gate Bipolar Transistor) are semiconductor devices designed for high-power switching applications. In actuator driver circuits, they function as electronic switches that control the flow of electrical current to motors, enabling precise speed, torque, and position regulation. MOSFETs excel in high-frequency, low-voltage operations, while IGBTs are optimized for high-voltage, high-current applications with moderate switching frequencies.

Working Principle

These devices operate as voltage-controlled switches. When a gate voltage is applied, it creates an electric field that modulates the conductivity between the source and drain (MOSFET) or collector and emitter (IGBT), allowing current to flow. In actuator drivers, they switch rapidly to generate pulse-width modulated (PWM) signals, controlling motor power by varying the duty cycle.
